MACHINE FOR THROWING SILK.

SPECIFICATION forming part of Letters Patent No. 398,359, dated February 19, 1889. Application ned December 2, 1887. sel-iu No. ans. 4 (No maten To all whom, t may concern.-

Be it known that I, JOSEPH E. TYNAN, of

of New Jersey, have invented an Improvement in Machines forThrowing Silk, of which the following is a specification.

spools and spindles. The tliivirigufoller 13 is upon the shaft 14 and receives its motion from the shaft 1 through suitable gearing, such as the wheels 16, 18, and 19 and pinions 15 and The present invention is a modification of and improvement upon the device for which 1.

i Letters Patent No. 364,784 were granted to me .I une 14, 1887, and a reference is hereby made to the said patent for such parts and their mode of operation as are shown herein.

The peculiar features of the present in ven tion will hereinafter be specially described and claimed.

In the drawings, Figure 1 is a vertical crosssection of the spindle rail and frame and olevation of the spools and parts at 'one side of the machine. Fig. 2 is a front elevation of one group of spools and parts acting with them. Fig. 3 is a plan view showing two groups of spindles-one at each side of the machine-and the belts for drivingthe same. Fig. 4 is an elevation of the belts and mechanism for driving and stopping the spindles. Fig. 5 is a modification of the stop mechanism actuated by the fallers. Fig. (i is a plan view, in larger size, of the rocking lever and faller-stand, the fallers and detector being in section. Fig. 7 is a detached elevation of the detector and the parts actingwith it, and Fig. Sis a .detached view of the brake-plates and t-he device for holding down the pulleys and spindles.

The frame .4,spindle-rail B,and longitudinal frame C are of ordinary character, and the shaft l is provided with the drum 2 or range of pulleys. I prefer to have one pulley 4for each pair of belts that pass to opposite groups of spools. The spindles 3, 4, and 5 occupy triangular positions, as seen in Fig. 3,

and the rin g-rail 9 is made to rise and fall asv the winding of the thread proceeds upon the spool 8. The spools 6 and 7 on the spindles 3 and 4 supply the threads, which are twisted by the revolution of the spindles and laid together by the revolution of the spindle 5 in the opposite direction. The threads pass from the spools G and 7 up against the guide-1ingers 66, and are wrapped around them to give the proper tension by the revolution of the The feed-roller 11 is upon the shaft 56, and the ends thereof are supported in the brackets 55, and there is a starting-lever, 80, pivoted upon one of the brackets 55, and passing below the shaft 56 near one end thereof.

All the parts before named correspond to those set forth in my said patent, No. 364,7 84, and do not require further description. herein. I, however, remark that there are not any loose pulleys on the spindles, and the drivingroller 13 is made as a cylindrical shell with mortises 74 through the shell, instead of recesses cut into the surface of the roller.

I do not make use of a guide-roller in front of the feed-roller; but I employ a traversebar, 24, reeiprocatcd longitudinally by suitable means, such as by a crank-pin, 25, and link or connecting-rod 2U. The crank-pin 25 is at the upper end of a shaft, 27, in bearings upon one of the frames A, and receiving motion from a worm, 28, on the shaft14, acting upon the worm-wheel 29 on the shaft 27. By

this means the traverse-bar 24 receives a small tical above the pivots on which they swin The hooks 37 of the fallers extend forward from the pivots, and they are nearly counter poised by the weight portions of each faller,

little pressure of the faller against the thread.'

The threads, after they leave the guide-fingers G6, pass up behind and over a thread-support, 35, preferably in the form of a glass rod, upon the standardr 3G, that is fastened to the faller IOO stand or frame 42, and then the threads pass portion of the feed-roller ll projects beyond' the end ot' the driving-roller lf3; hence there is ample room Afor the introduction ot the detector, which is placed just below the feedroller, and brings the stop-motion into action in case the thread leaving the roller becomes I one of the tallers descends1 and the said roller` vl3 acts against the claw to move thevlevcr 65 entangled with that part of the thread on the roller, as sometimes occurs when there are knots or rough places on the threads. It there were nothing to stop'the parts at'y such a time, the lfeed-roller would draw the thread from the back bobbin aswell as from the front ones, and lap them around itself. This danger I entirely avoid, lior when thcthread leaving the roller becomes entangled with the thread on the roller the angle ot' the thread below the roller is changed to the position shown by dotted lines in Fig. 7, which allows thc arm of the detector to fallforward and cause the stop mechanism to be brought into action, as hereinafter described.

At the back end ot the starting-lever SO the hanging latch 40 is pivoted, and the link 50 hangs from the stud 41, which is to the rear ot the latch-pivot, so that the weight of the link 50 and parts ot' the stop-motion therewith connected, or a weight upon the link 50, asseen at 95, may tend to swing the lower end ofthe latch 40 toward the trame C and the taller-stand 42, that is bolted upon such frame C. The shoulder 43 on the latch 40 rests upon the back end, 44, ot the taller-stand 4i when the parts are in the normal posit-ion, and when the stop-motion is brought into action the latch 40 is pushed backwardly to move the shoulder 43 ott' the part 44 and allow the parts to drop, and the liange 45 limits the downward motion, and the finger 46 being in front of the link 50 prevents the latch 40 being swung too far back by the action of the are made as vertical weights Q slightly to the i rear of the pivots on which they swing, so as nearly to counterpoisc the weight and leverageof the hook ends 237 of the fallers7 thus causing the iallers to bear very lightly on the threads and prevent the danger' of t-he taller moving and carrying the thread with it and stopping the action when a thread has not broken; but as soon as a thread breaks and the vtaller-hook moves away from the threadsupport 255 the eliieien c y of the same in bringing `into action the stop mechanism is increased, because the weight ot the laller acts with increased'leverage as it descends toward a horizontal position, and there is a projecting finger, (52, on the l'aller to act upon the rocking lever G5 when the threads break and the taller descemls. This lever is pivoted at G23 in the swinging-yoke 67, that is within a mortise in the taller-stand and is pivoted to the latter at 69. The rear end of this lever 65 is the heaviest, so that in` a normal position it rests upon the part 44, and upon the lever 65 is a stud or claw, 69, that comes into oneof the mortises in the driving-roller 13 whenever endwisc, the yoke G7 swingingwhile this movement takes place, and the back end of' this'lever 65 pushes the latch 40, so that the shoulder 43 passes'ol't its support, and the link 50 and stop mechanism descend to stop the act-ion of the belt that rotates the' group of spindles, as hereinafter described. Asthc rocking lever G5 is moved backward and unlatches the latch 40, such latch falls and' the iiange 45 carries down with it the rear end-ot' the said rocking lever 05, and thereby keeping the claw G9 clear from the driving-roller, and simultaneously the yoke (37 swings forward again by its own weight, carrying with it the rocking lever 65 and returning it to the normal position; but the rocking lever cannot rise again by the weight of the faller to cause the claw to come into contact with the drivin g-roller, because the iiange 45 remains above thc rear end of the rocking lever until the latch 40 is raised to start the parts.

The detector (i4 1s pivoted at 70 upon the taller-stand 42, and it stands nearly vertically, and the wire thereof is behind the threads as they are laid together and pass down from the feed-roller] l. Vhen the detector G4 falls forward, a finger, 7], that projects from the lower part of the detector in below the rocking lever G5, raises such rocking lever and causes the claw 69 to engage the roller 13 and bring into action the stop mechanism. This operation takes place whenever the doubled thread breaks, or whenever the threads bccome entangled and commence to wind on'the feed-roller, as before described, or whenever the thread slackens in consequence of a ringtraveler being thrown oil. It will now be apparent that when the attendant has mended a thread and he is about to start the parts he places one linger under the front end of the rocking lever G5, to prevent the weight ot' the fallcrs moving said lever G5 and bringing the claw again into contact with the roller 13, and then with the thumb the outer end of the IOO IOS

mechanism of the spindles, and to bring the feed-roller il into contact with the drivingroller lf3, and the other hand of the operator is free to guide the threads to place as they are drawn up, and there is no separate operation required to pass the threads into the hooks of the taller-wires, because it is only necessary to guide the threads as they draw up and cause them to pass in below the hooked ends of the Ytaller and lead ott between them to the linger.

The revolutions of the spindles o and T wrap the threads around the guidetingers (lll, and the revolution of the spool S throws the descending thread within the stationary guide-hook S2, and the operatioi'is proceed automatically.

The movement endwise oi the traverse-bar 2t and guides c is sufficient to traverse the threads slightly upon the standing guide-tinger 38 and the feed-roller 11, and against the deteetor-wire 64 and shaft l-t and fixed guide S2, and `prevent the said parts becoming worn into grooves or notches. These parts are horizontal and parallel to each other at the portions where the thread touches them, so that the thread. can be traversed freely upon them.

If the swing-yoke 67 is dispensed with, the rocking lever U5 can be pivoted upon the fallenst-am'l, as shown in Fig. In this case the claw U9 will be made with a pusher, 7 5, that slides in supports on the rocker-lever G5, so that the pusher and claw will be moved together by coming into contact with the end of one of the mortises in the roller 13 to act upon the latch L t and stop mechanism. In this ease a spring, 7G, is used to return the pusher and claw to their normal position. The parts ot' the fallers and detector remain inmhanged. The belt 230 passes around the respective pulleys -l al 95 of the spindles f3, et, and 5, as in aforesaid patent; but the tightA ener-pulley 32 acts in connection with vthe stop mechanism, the lever 33 of said pulley :l2 being pivoted at Si and suspended by the link 50. licnee when the latch t() and link 50 are raised b v the starthigdever .Q0 the belt is tightened, and when the ,latch et() is pushed baelc and drops until its .fiange .l rests on the back end oi' the rocking lever the pulley 32 is lowered andthe belt loosened, and it becomes incapable of driving the spindles; but there would be a slow movement, by the `friction of the parts were it not that I apply a brake to the respective pulleys and spindles.

The brakeplatc 5l is a loose separate plate, and is adapted to occupy the space between the three triangula1'pl:wed spindles, 4, and 5,'and it is below the pulleys 03 (it 95, and rests upon the tapering upper part ot' the spimlle-sockets or upon projections thereon; and the projecting ends of the plate 5l are curved to conform circumferentially to the spindle-sockets, and the lever 33 has an end that passes in beneath the middle of the brake-plate 5l, so that when the pulley 32 is lowered and the belt slackened the brake plate 5l is lifted bodily into contact with the under side of the pulleys 93 9i 9,5, the ends of the plate 5l adapting themselves and tak ing an even bearing upon the under sides ot the said. pulleys, so as to stop the same by the friction as nearly simultaneously as possible.

'Upon the brake-plate 51, at one side oli the machine, i a tin ger or stud, 5i),to prevent the slack belt slipping ott' the pulley 9i; but I find that at the other side ofthe machine the lever near the end that passes beneath the brake-plate serves this purpose. Upon the levers 33 there are guide-fingers 54 and 55 to prevent the belts slipping oti the tighteningpulleys 32. The parts at the two sides of the machine that act with the respective groups ot' pulleys are alike, with the exception of the fingers or studs and guides for the belts, as seen in Figs. 3 and at.

It will be apparent that the parts otI the stopanotion will not be changed in their mode of operation it' the force required to unlatch the catch 40 is derived ifrom a separate shaft instead of from the driving-roller 13 and shaft 14e. An illustration of the manner in which this can be done is shown in Fig. 7, wherein the rocking lever (i5 has a lateral and rearward projection or continuation that passes at one side of the latch 40, and has at or near itsl end the claw 69 to be acted upon by a cam or tooth on a revolving shat't, o7, in a convenient position for giving the required movement' to the parts when a taller or detector acts on the rocking lever. The projection or claws, against which the revolving device acts to give end motion to the rocking lever and liberate the stop-motion, may be varied according to the character and location of the revolving device without altering the mode ot' operation of the parts Upon the brake-plates 5l there are curved lin gers 5R, that pass over the edges of the re spective spindlepulleys, so that the pulleys are free to revolve without touching these iingcrs but when eitherspool'or bobbin is pulled ott.' its spindle said spindle cannot become detached because the overhanging ti nger liinits the upward movement of the spindle and its pulley. The vertical guide-pin 59, attached at its upper end to the brake-plate 5l, serves 'to guide said plate, and a cross pin or head at the lower end of the pin 59 forms a stop to prevent the brake-plate being lifted too high.

I claim as my inventionl. The combination,with the spindles, their sockets and pulleys, of a driving pulley or drum and belt, a tightening-pulley, and a lever for supporting and moving the tightening-pulley, a suspending link and latch for holding up the pulley-lever, the fallers, and mechanism for moving the latch off its support and allowing the pulley to descend and slacken the belt when one of the threads is broken, and a loose brake-plate below the spindle-pulleys and between and guided by the spindle-sockets, which brake-plate is lifted by the lever of the tightenerpulley and IOO IIO

pressed against the underside of the spindlepulleys to stop their rotation when said belt is slackened, substantially as set forth.

2. The combination, with the group of three spindles, their sockets and pulleys, of a driving pulley or drum and belt, a tightening-pulley and lever for the same, and a loose brakeplate below the spindle-pulleys and between and guided by the three spindle-sockets, which brake-plate is lifted by said lever and pressed against the under side of the spindle-pulleys to stop their rotation when the driving-belt is slackened, substantially as set forth.
